My 1989 Nissan Pick Up 2.4 4 cyl had intake/exhaust plugs. Even at 350,000 kms, it went in for an e-test and the mechanic was shocked at how low the emissions were.

Great powertrain, but a shame about the rampant rusting on the body.

Awsome write-up! I have to do my wife's 08 next week. The manual recommends changing the "top row" at 30K miles, she has about 37K. Why would you only need to change half of them? Should I go ahead and do all 16 or just the top rows as recommended? When I asked a jeep tech about it, he said it was only a way to get the jeep in twice for the same service... 8 plugs now, and 8 plugs later.
Also, what plugs would you recommend for her 08?

Old Thread, but wanted to send some thanks your way.

Just changed my spark plugs out today and it was a breeze because of the step by step I could study before starting.

I didn't even need to refer back to this Thread because your writeup was very well done.

Definitely was glad I picked up 1) a adjustable neck socket wrench (3/8") and 2) a multi-angle 5/8" spark plug socket. Came in handy during the passenger side rear plug!

Here's a question though - As I was changing the passenger side plugs (in the back) I found a male end of a electrical cord.... No idea what is was for or connected to... Does my used Jeep have a engine warmer hooked up that I wasn't told about?

Is that the chord that plugs into the temperature sensor on the air box?

I'm not sure, would it look like a straight-up-electrical plug?

On the bright side, with the new sparks my Jeep idles at about 650-700 rpm.

Before it was at 500 rpm and would flutter every once in a while.

Block heater is 600 Watts and if you trace the cord, you'll find it leads to a freeze plug next to the starter.

Plug it into a timer and have warm coolant (100-120 degrees in 20-30 F weather if parking outside) without starting the engine and letting it idle before you set off on cold mornings. 1-2 hours should be enough plug-in time if you want to use it as I described.

WORTH the price of admission!!! NOW I know why I can't find a plug wire SET for my 287 Commander!!!
